Graph the function

f(x)=3x+5

(remember slope intercept form f(x)=ax+b where a is slope, b is y-intercept) Start by plotting the y-intercept, then count the slope to the next point

Answer explanation

Graph:

y= -1/2(x) +3

The graph of linear function g passes through the points (-7, -4) and (7, 6) as shown.

The slope is ​ (a)   , and the y-intercept is ​ (b)   .
